Development and industrial application of dechlorination agent for reformate oil
摘要
Abstract
Objective The aim is to prepare reformate oil dechlorination agent with high chlorine capacity and realize industry application.Methods The dechlorination agent for reformate oil was prepared by using pseudo-boehmite as the carrier,loading two-component activator,screening the pore-forming components,adjusting the pore structure and optimizing the reasonable molding and baking process.The physico-chemical properties of the dechlorination agent were characterized by using BET,XRF,SEM,and the dechlorination agent performance was evaluated by using a 20 mL small test device.Results At a reaction temperature of 50℃,a volumetric space velocityof 3 000 h-1,and a chlorine mass fraction of 60 000 mg/kg in the reaction gas,the chlorine capacity of self-made dechlorination agent was 18.4%.The dechlorination agent product was applied to the reforming unit of CNOOC Ningbo Daxie Petrochemical Ltd.,the differential pressure before and after dechlorination tank was less than 50 kPa,and the chlorine mass fraction at the outlet of the dechlorination tank dropped to below 0.5 mg/kg.Conclusions The influences of adding different types and contents of active compounds and pore-forming agents,as well as the baking process parameters on the properties of dechlorination agent was clarified,which could provide reference for the preparation and optimization of similar dechlorination agents.关键词
